| What do you get when you mix a space fighter with 12 tonnes of cytoplasm? | Enter Membrane Massacre. The year is 2160. A deadly bacteria is sweeping the world -- the likes of which medical science has never encountered before. The world's best doctors have failed to find a cure. And so what is the fate of mankind? Ente... |

| Predictable sin/cos rounding errors? | This really smells like a rookie mistake to me, so I felt this belonged best in the beginners' forum. The relevant code in question is as follows: const float rot = 45; float cos_v = cos(rot*D2R); float sin_v = sin(rot*D2R); for(... |

| Game timing: maintaining a constant number of updates-per-second | My game project currently uses frame-rate independant timing, such that it will attempt to update game logic at a constant 60 times per-second irregardless of what the framerate is. This works by gauging how long the previous frame took to render, an... |

| [C++] Evading naming conflicts | I'm writing a program that makes use of a Curses library, which defines a clear() function amongst many others. However, I'm also using the STL 'string' class, which defines a method clear() as well. Unfortunately, these two are conflicting. Is there... |

| [Solved] wglUseBitmapFonts() not available with SDL? | Greetings! I am currently developing with the infamous SDL+OpenGL library combination, and am at the point where I need to get some text going onscreen. From the various font-rendering methods available via OpenGL, I found bitmap fonts the mo... |

| [MSVC++ 2005 Express] Configuring a 'current' directory? | A beginner-level-ish question that has been eluding me for the last couple of days, regarding Visual C++ 2005 Express: How does one go about configuring a directory that the program will 'run' from? I need to access various files to load game... |

| Exploring Metaballs and Isosurfaces in 2D | Quote:Original post by MrRowl The article is nice as far as it goes, but it's a shame that there's not even a mention of other rendering methods - in particular marching cubes (and the equivalent in 2D) - since in practice (I assume) per-pixel probi... |

| Exploring Metaballs and Isosurfaces in 2D | Thank you for all of the positive comments. I'm looking forward to pumping out some more articles in the (near!) future. [smile] |

| Predictable sin/cos rounding errors? | @Erik: Thanks for the response! And you're 100% right: for the given shape that I'm using, they simply cannot possibly line up the way I wanted them to. I'll have to take a different approach to the rendering. Rating++'s all around. Sorry for not... |

| Predictable sin/cos rounding errors? | Quote:Original post by Erik Rufelt Does pgm->render always draw the same image? Or is the image drawn also rotated? In this case it's the same image drawn exactly the same each time -- just a straight-up SDL_BlitSurface() call of the same ima... |

| Predictable sin/cos rounding errors? | Quote:Original post by Splinter of ChaosWhat happens if rot is zero? Try rotating it real-time. Do you have a problem for ANY angle? Sorry, I must have not been clear in my original post: these off-by-one errors occur at every angle. I just chose... |

| Predictable sin/cos rounding errors? | @swiftcoder & Mike: I'm using SDL for the rendering portion, which uses integer coordinates in rendering. I've tried both regular cast-to-int rounding, as well as substituted in a proper rounding function, and neither account for the error in drawing... |

| Predictable sin/cos rounding errors? | Quote:Original post by MikeTacular Why not try rendering it without precomputed values and see if there are the same artifacts? Actually, try using floats for the positions. Casting each tile's position to an int isn't going to help your accuracy... |
